Preparation method of toona sinensis fermented black tea

The invention discloses a preparation method of toona sinensis fermented black tea. The preparation method comprises the following steps: (1) withering; (2) rolling; (3) fermenting; (4) primarily drying through gross fire; (5) drying by final fire; (6) spreading for airing; and (7) packaging. According to the preparation method, toona sinensis leaves are adopted to be fermented to prepare tea for the first time, and are properly withered and fermented, so that the enzyme activity of the fresh leaves is activated, macromolecule nutrient substances in the fresh leaves are degraded into absorbable micromolecule substances, the content of aqueous extracts is increased, and nutrients in tea water are rich; furthermore, through sufficient fermentation, the bitter taste of the finished tea is improved, so that the tea is mellow to be easily accepted by people. Meanwhile, a conventional process of drying by final fire can be changed, and a two-time drying method is adopted, so that the toona sinensis fermented black tea has special quality. The content of functional ingredients such as total flavonoids and soluble sugar can be increased, so that the toona sinensis fermented black tea is endowed with a certain health care function.
